Download or read book Engineering Of with Lipases written by F.X. Malcata and published by Springer Science & Business Media. This book was released on 1996-03-31 with total page 648 pages. Available in PDF, EPUB and Kindle. Book excerpt: The innovative uses of lipases in a wide variety of organic syntheses and the modification of existing fats and oils have increased exponentially over the last five years, due to the increasing availability of lipases from (genetically engineered) microbial sources, coupled with their special capacity to act as catalysts at hydrophilic/hydrophobic interfaces. As a result of the structural characterisation performed during the same period, applications of these lipases can now be developed in a much more rational way. Engineering of/with Lipases presents two major topics: the design and production of lipases with desired, preselected properties, and the use of lipases for desired applications. Audience: Doctoral and post-doctoral crystallographers, biochemists, geneticists and enzyme kineticists. Food, chemical and biochemical engineers. The former will learn about the practical aims and constraints associated with industrial applications of lipases, enabling them to design lipases for specific purposes. The latter will learn how to take advantage of the structural knowledge of lipases and their metabolic genesis to better design media, processes and products in terms of biochemical and technical feasibility.

This book was released on 2018-10-08 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enzymes are currently used in various industries, most commonly in food, detergents, and pharmaceuticals production. Lipases are hydrolytic enzymes that demonstrate great potential as an alternative to conventional catalysts in a number of industrial applications. A complete understanding of enzymes, and their proteins structure and environmental behavior, can greatly aid in the further development of industrial applications. Supercritical Fluids Technology in Lipase Catalized Processes provides basic information about enzymes, their sources, reaction kinetics, and main industrial applications. The book focuses in lipases. their main sources, structure, and features, with an emphasis on their specificity and interfacial activity, and presents proven techniques for isolating, extracting, and purifying. Comprised of six compact chapters, this comprehensive guide introduces: Immobilization techniques and immobilized lipases that allow repeated use (which is essential from an economic point of view) Different bioreactor configurations using immobilized lipases The latest information on the available technologies in lipolytic reactions The advantages of nonaqueous media in biochemical synthesis over aqueous and solvent-free systems Material on the use of lipases in nonaqueous media to overcome the drawbacks usually encountered with the use of conventional chemical catalysts The use of supercritical fluids (SCFs) as a green alternative reaction medium Factors affecting the physical properties of lipases in this medium and, hence, their activity and stability A case study using supercritical carbon dioxide (SC-CO2) for biodiesel production Novel, cutting-edge technology, using immobilized enzymes to reduce the overall production cost Supercritical Fluids Technology in Lipase Catalized Processes outlines the main industrial applications of common enzymes and discusses relevant challenges and innovations emerging in the field.
Download or read book Enzyme Immobilization written by Rowan Austin and published by Scientific e-Resources. This book was released on 2018-12-19 with total page 348 pages. Available in PDF, EPUB and Kindle. Book excerpt: An enzyme is a protein, or protein complex, that catalyses a chemical reaction. Like any catalyst, enzymes work by lowering the activation energy of a reaction, thus allowing the reaction to proceed to its steady state or completion much faster than it otherwise would; the enzyme remains unaltered by the completed reaction and can therefore continue catalysis. An immobilized enzyme is an enzyme attached to an inert, insoluble material-such as calcium alginate. This can provide increased resistance to changes in conditions such as pH or temperature. It also lets enzymes be held in place throughout the reaction, following which they are easily separated from the products and may be used again-a far more efficient process and so is widely used in industry for enzyme catalysed reactions. An alternative to enzyme immobilization is whole cell immobilization. Carrier matrices for enzyme immobilisation by adsorption and covalent binding must be chosen with care. The manufacture of high-valued products on a small scale may allow the use of relatively expensive supports and immobilisation techniques whereas these would not be economical in the large-scale production of low added-value materials. A substantial saving in costs occurs where the carrier may be regenerated after the useful lifetime of the immobilised enzyme. This book is simple protocols for the immobilization of enzymes and cells that could be useful for application at industrial scale, novel protocols for immobilization in the future, and new chemical reactors able to overcome the limitations of a number of immobilized derivatives.
Download or read book Immobilization of Enzymes and Cells written by José M. Guisán and published by Springer Science & Business Media. This book was released on 2008-02-05 with total page 447 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enzymes and whole cells are able to catalyze the most complex chemical processes under the most benign experimental and environmental conditions. In this way, enzymes and cells could be excellent catalysts for a much more sustainable chemical industry. However, enzymes and cells also have some limitations for nonbiological applications: fine chemistry, food chemistry, analysis, therapeutics, and so on. Enzymes and cells may be unstable, difficult to handle under nonconventional conditions, poorly selective toward synthetic substrates, and so forth. From this point of view, the transformation—from the laboratory to industry—of chemical processes catalyzed by enzymes and cells may be one of the most complex and exciting goals in biotechnology. For many industrial applications, enzymes and cells have to be immobilized, via very simple and cost-effective protocols, in order to be re-used over very long periods of time. From this point of view, immobilization, simplicity, and stabilization have to be strongly related concepts. Over the last 30 years, a number of protocols for the immobilization of cells and enzymes have been reported in scientific literature. However, only very few protocols are simple and useful enough to greatly improve the functional properties of enzymes and cells, activity, stability, selectivity, and related properties.

Download or read book Enzymes in Nonaqueous Solvents written by Evgeny N. Vulfson and published by Springer Science & Business Media. This book was released on 2008-02-05 with total page 677 pages. Available in PDF, EPUB and Kindle. Book excerpt: Enzymatic catalysis has gained considerable attention in recent years as an efficient tool in the preparation of natural products, pharmaceuticals, fine chemicals, and food ingredients. The high selectivity and mild reaction con- tions associated with enzymatic transformations have made this approach an attractive alternative in the synthesis of complex bioactive compounds, which are often difficult to obtain by standard chemical routes. However, the maj- ity of organic compounds are not very soluble in water, which was traditi- ally perceived as the only suitable reaction medium for the application of biocatalysts. The realization that most enzymes can function perfectly well under nearly anhydrous conditions and, in addition, display a number of useful properties, e. g. , highly enhanced stability and different selectivity, has d- matically widened the scope of their application to the organic synthesis. Another great attraction of using organic solvents rather than water as a reaction solvent is the ability to perform synthetic transformations with re- tively inexpensive hydrolytic enzymes. It is worth reminding the reader that in vivo, the synthetic and hydrolytic pathways are catalyzed by different enzymes. However, elimination of water from the reaction mixture enables the “reversal” of hydrolytic enzymes and thus avoids the use of the expensive cofactors or activated substrates that are required for their synthetic count- parts.
